A cam-follower release mechanism for fiber optic modules with side releases. The cam-follower release mechanism translates rotational motion into linear motion. The release mechanism has a rotatable bail lever with a cam lobe that pivots about a pivot point and presses against a bearing surface of the fiber optic module. The release mechanism further has a base with a pin about with the rotatable bail lever may pivot and a sliding fork with sliding side actuators and delatch actuators at each end. As a follower, the base and sliding fork is linearly pulled as the rotatable bail lever is rotated. As the sliding fork is pulled out, the delatch actuators at each end push in on side tabs of a cage into which the fiber optic module may be inserted. The release mechanism further has a spring to apply a force against the rotation of the rotatable bail lever to return it to home and retain the release mechanism moveable coupled to the fiber optic module. The fiber optic module further includes opto-electronic devices mounted to a printed circuit board, and a housing.

An angle detection apparatus comprising a magnet rotor having a multi-pole segment magnet, and a magnetic sensor for detecting the direction of a magnetic flux generated from the multi-pole segment magnet; the multi-pole segment magnet having pluralities of magnetic poles along the rotation direction of the magnet rotor, the magnetic sensor comprising a magnetosensitive plane having pluralities of spin-valve, giant-magnetoresistive devices each having a pinned layer having a fixed magnetization direction and a free layer having a magnetization direction rotating in response to the magnetic flux direction; and the magnetic sensor being positioned relative to the magnet rotor, such that the magnetosensitive plane crosses the magnetic flux, with perpendicular magnetic flux density components having different amplitudes on the magnetosensitive plane.

An adjustable dual-screen monitor stand includes a base member having an upright post, an upper bushing and a lower bushing mounted on the upright post at different elevations, a first cantilever swivel screen mount including a first lower swivel arm, a first upper swivel arm and a first screen holder pivotally coupled to one another and pivotally supported on the upper bushing to hold a first flat display monitor and to allow adjustment of the angular position of the supported first flat display monitor, and a second cantilever swivel screen mount including a second lower swivel arm, a second upper swivel arm and a second screen holder pivotally coupled to one another and pivotally supported on the lower bushing to hold a second flat display monitor and to allow adjustment of the angular position of the supported second flat display monitor.

The manifold type pipe structure according to the present invention is characterized in that at least branch pipe is formed at a pipe passage having a flow hole through which fluid flows, and an input valve is formed at an end portion of the pipe passage, and a joint coupler forming an output valve at the other end portion is prepared, and an output valve of a joint coupler of the other places is joint-connected with a limited rotation angle at an input valve of at least one joint coupler.

A hinge assembly and a mobile terminal are disclosed. The hinge assembly can include: a torsion spring; a shaft, which penetrates through the torsion spring; a bushing, coupled to one end of the torsion spring and to one side of the shaft; a holder, which is coupled to the other end of the torsion spring, and which the shaft penetrates through; a sliding cam, which is coupled to the other side of the shaft, and which may move in linkage with the shaft; a fixed cam, which engages the sliding cam; a compression spring, which is positioned between the holder and the sliding cam, and which may place the sliding cam in close contact with the fixed cam; and a housing coupled to the holder and the fixed cam. Thus, the mobile terminal can be unfolded automatically using just a few number of parts without requiring energy consumption.

An optical modulation device or an optical device including the same includes: a first plate and a second plate facing the first plate; and a liquid crystal layer between the first plate and the second plate and including a plurality of liquid crystal molecules, wherein the first plate includes a plurality of first electrodes and a first aligner, the second plate includes at least one second electrode and a second aligner, and an alignment direction of the first aligner is substantially parallel to an alignment direction of the second aligner and wherein portions of the first plate, the second plate, and the liquid crystal layer between the first and second plates are individual units.

A folding chair includes a lower assembly including a lower block and three or more legs pivotally connected to the lower block; an upper assembly including an upper block and three or more arms pivotally connected to the upper block; a middle assembly connecting the upper assembly and the lower assembly; and a flexible seat including the same number of end portions as the number of the arms, wherein each end portion is arranged at an end of each arm away from the upper block, wherein the upper block is provided with a stop portion to limit the rotation angle of the arms, and wherein the arms are retractable, the flexible seat is arranged to be in a relaxed state when the arms are in a retracted state, and in a tight state when the arms are in an extended state.

An artificial eye structure rotates an artificial upper eyelid via the attraction between a number of electromagnetic elements disposed in a line and a magnet. The rotation angle of the artificial upper eyelid can be controlled by selectively magnetizing the electromagnetic elements.

A hinge assembly (300) for use in a flat display monitor includes a support seat (10), a base seat (20) and a pivot mechanism. The support seat has a cutout (164) defined by two opposed side surfaces. The base seat includes a resisting member disposed thereon. The pivot mechanism rotatably connects the support seat to the base seat. A resisting member (94) on the base seat is movable in the cutout of the support seat upon rotating of the support seat relative to the base seat. The two side surfaces are configured to engage with the resisting member when the support seat rotates relative to the base seat in a manner so as to prevent the resisting member from moving further to limit a rotation angle between the support seat and the base seat.

The actuator device includes: a motor housed in a case having a cover; an output gear driven to rotate by the drive shaft of via a deceleration gear; an output shaft rotatably supported by the case and rotating together with the output gear; and an output cam mounted on the output shaft; the actuator device having a receiving recessed part accommodating a stopper element on the top surface of the output gear, a stopper element rotatably mounted on the output shaft facing inside the receiving recessed part, and a locking projection part that is locked to and separated from the projection part of the output shaft and a stopper on the stopper element; and stopper where each stopper of the stopper element is locked to the inner surface of the cover to limit the rotation angle of the output gear.

A USB memory stick includes comprises a casing comprising opposing top and bottom sides and a bottom opening in said bottom side, a PC board comprising a USB interface circuit and a memory chip package, a tray holding the PC board in the casing, a safety hook for fastening to a belt or strip-like object, and a hinge coupled between the casing and the safety hook for allowing a limited angle of rotation between the casing and the safety hook.
